Abstract:
A substrate manufacturing facility includes a lower molding plate and an upper molding plate. A resin supply tray provides resin powder to a top surface of the lower molding plate. The lower and upper molding plates may compress a substrate and the resin powder. The upper molding plate has multiple apertures. The apertures are densely formed on a front side of the upper molding plate. The front side of the upper molding plate contacts the substrate. The apertures have diameters smaller than diameters of the resin powder. The substrate manufacturing facility includes a vacuum pump, a ventilator, a conduit, a controller, and valves. The substrate manufacturing facility can adsorb a circuit board using adsorption pressure from the vacuum pump and clean residue from the upper molding using exhaustion pressure from the ventilator.
